getSystemData() returned 23: Failed writing received data to disk/application

When running SMAspot -u I am receiving the message below:
__getSystemData() returned 23: Failed writing received data to disk/application
__
The PVoutput is updating fine and the csv files and csv event file are also created. I am running Windows 8.1 64 bit. I am wondering what is the meaning of this message.

This looks like an access error on win8... what happens when you run SMAspot "as administrator" - Just as a test
however, this is not a critical issue; everything should work fine
what is the output of -v5 ?

Sorry, it's a bit confusing... I mean the output of verbose logging (SMAspot.exe -u -v5)
I have to set up a virtual W8.1 environment for this to investigate, so it can take some time. But in the meantime you don't have to worry about this.
